DSPBrik™ II X6A1250 Wideband ADC with FPGA
The DSPBrik™ II X6A1250 analog-to-digital converter (ADC) card combines a 10 bit analog-to-digital converter, with a large FPGA for high-performance digital signal processing. The ADC samples at up to 2.6 GSPS and has a 10 MHz to 5 GHz input passband, enabling digitization of signals in multiple Nyquist zones. The FPGA and ADC are controlled via an on-board microprocessor running embedded Linux.
The X6A1250 is ideal for acquiring wideband satellite communication signals. A typical application includes direct digitization of an L-band (950 MHz to 1750 MHz) output from a microwave block down converter.
Once the signal is digitized, the FPGA can be used to implement a number of different functions, such as sub-band tuning, demodulation, channelization, and spectral analysis. Processed data can be sent to other systems via multiple 10GbE interfaces. The X6A1250 is used as a core component of the DLSR2.
